"We do not know if this person is a student at the school or someone who may have walked onto the campus," Cox said. "We also don't know whether the person is still on campus grounds, so we're taking safety precautions while law enforcement performs a search."
By 3:30 p.m., the school remained on "campus protection," but students were expected to be released, in groups, into the Los Angeles Sports Arena parking lot at Martin Luther King Jr. Boulevard and Figueroa Street beginning at 4 p.m., said Monica Carazo of the Los Angeles Unified School District.
"Parents can pick up their children there," Carazo said. "No one has been hurt, there are no injuries and no shots were fired. We want parents to know their children are in good hands."
Carazo also said no one had been arrested.
